Abstract (en)
A semiconductor integrated circuit that is used for a stabilizing power supply circuit which supplies an output power supply voltage to a parallel connection of a smoothing capacitor and a load, from an input power supply voltage, includes an error amplifier that detects an error of the output power supply voltage, an output control circuit that is connected between the input terminal and the output terminal, a phase compensation circuit that is connected to the error amplifier, and a detection control circuit that is connected to the phase compensation circuit.
